Abstract: PURPOSE:To decrease the leakage of error detection by making at least a part of the data of the error correcting code series 1 into an error according to the condition of an error flag at the time or decoding former than the decoding based on the error correcting code series 1. CONSTITUTION:A regenerative signal from an optical pickup 3 is sent through an amplifying/PLL circuit part 4 to an EFM demodulator 5, demodulated, sent to a decoder 6 in a C1 series and a decoder 7 in a C2 series, and successively decoding-processed. In the decoder 7, according to the number of error flags and the pattern of the flags, etc., obtained when the C1 series is decoded before the decoding of the C2 series, for example, the possibility of burst error generation is presumed, and the data without the error flag are processed so as to hoist the flag.

Abstract: PURPOSE: To enhance reliability of a compressor by arranging a heat transfer fin, a net and a direction switch for controlling refrigerant flow in a liquid receiver/liquid separator incorporating a heat exchanger thereby enhancing the efficiency of cooling/heating operation and recovering oil smoothly to the compressor. CONSTITUTION: A direction switch 70 mounted on one side face of the liquid receiver 62 of a liquid receiver/liquid separator 60 incorporating a heat exchanger opens or closes cooling piping P2 or heating piping P1 depending on cooling or heating. Refrigerant flowing into the liquid receiver 62 is delivered through a refrigerant outlet pipe 100 or 101 to a pressure reducer 40 or 41. Consequently, refrigerant flow can be controlled easily. Refrigerant delivered to a heat exchanger 30, 50 and evaporated is delivered through a four-way valve 20 and a flow-in pipe 64 to a liquid separator 61. Evaporated refrigerant is fed, as it is, to a compressor 10 through a suction pipe 63 and liquid refrigerant is evaporated through a heat transfer fin 67 before being fed to the compressor 10. Consequently, unevaporated refrigerant is evaporated sufficiently.

Abstract: PURPOSE:To permit extremely quick changing over of optical connectors by changing over the 1st and 2nd optical connectors instantaneously when the contact parts of a pin penetrated through the two connectors and another in come nearly flush with the butt faces of the two connectors in the process when the latter pin successively pushes the former pin. CONSTITUTION:The 2nd and 4th optical connectors 11B, 11D are pushed up by a moving base 22 and the 2nd optical connector 11b rises until the connector abuts on a stopper 25 at the point of the time when the contact points of the front and rear pins 13A and 13C and the contact points of 13B and 13D emerge from the 1st and 3rd optical connectors 11A, 11C as the pins 13C, 13D are successively pushed in. The 4th optical connector 11D is thereby brought into abutment on the 1st optical connector 11A, and, therefore, the pins 13C, 13D are further pushed in until the half of the front end side of the pin 13C enters the pin hole of the 4th optical connector 11D. The 1st and 4th optical connectors 11A, 11D is then put into the connected state. The quick changing over of the optical connectors is thus permitted.

Title: Dehydration method for filter press
Inventor: TANII MASAO
IPC: C02F11/12
Filed: 1988-03-24
Abstract: PURPOSE:To dehydrate sludge contg. fine particles efficiently by performing a first dehydration of coarse sludge in a sludge generated in a civil engineering work, then performing a second dehydration by feeding the sludge contg. residual fine particles to a same filter press. CONSTITUTION:If a sludge generated in a civil engineering work is dehydrated in a stage, a layer of fine particles is formed to 2-3mm thickness on an inside surface of a filter cloth which inhibits permeation of water when the layer is pressed. Accordingly, voids for permitting permeation of water are left after performing a first dehydration for coarse sludge in the whole sludge and forming a layer of the coarse particles on the inside surface of the filter cloth. When a sludge contg. fine particles is fed succeedingly, the fine particles in the sludge pass through a layer of the coarse particles, so the fine particles are caught by the layer of the cake of the coarse particles. Thus, a thick layer having 10-20mm thickness is formed, a large amt. of sludge contg. fine particles as much as several times in quantity as compared to conventional dehydration process where a sludge contg. both fine particles and coarse particles is dehydrated in one stage.

IPC: G02B26/10
Filed: 1978-06-14
Abstract: PURPOSE: To reduce the distance between a light source and a disc and reduce size and cost by integrating the light source and actuator and oscillating the light source in two directions.  
     CONSTITUTION: Permanent magnets 6, 7 are disposed in an excited state as shown in the figure. Exciting current at which yoke ends 20-1,21-1 become of the same pole (N pole) is flowed to the coils 24, 25 of electromagnets 20, 21. In this state, a holder 4 mounted with a light source 3 is held in a stable state. To move the light source 3 in the + Y direction, the direction of the current flowed in the coil 24 is changed so that S pole is made at the yoke end 20-1 of the electromagnet 20. Then, the permanent magnet 6 is attracted to the yoke end 20-1 side of the electromagnet 20 and in contrast, repulsion force acts between the permanent magnet 7 and the yoke end 21- 1 of the electromagnet 21. Since the permanent magnets 6, 7 are fixed to the holder 4 through stanchions 8, 9, the light source 3 moves in the + Y direction. To move the light source 3 in the - Y direction, the current is so flowed that the yoke end 20-1 becomes N pole and the yoke end 21-1 of the electromagnet 21 becomes S pole. The movement in the X axis direction is accomplished by the similar method.
